Application November 16, 1945, Serial No. 629,183 i Claims.

The present invention relates to ldoor frame construction and more particularly to the means for securing a vdoor frame in position in such a manner that a wall or partition may be formed therearound.

It is an object of the present invention to pro vide a novel means for securing a door frame in position with relation to the floor and ceiling of a building prior to the forming of the wall or partition of which the door frame becomes an integral part.

VIt is a further object of the present invention topro'vide two studs with clamping means for seeming a door frame in position between a iioor and a ceiling of a building prior to the forming of the wall or partition.

It is a further object of the present invention toA provide a novel clamping means to position a door frame between a ceiling and a floor of a building and providing said clamping means with a plurality of adjustments according to the size stud used in positioning the door frame.

It is a further object of the present invention to provide a plurality of clamps with a'plurality of upright supporting members to position a door frame in its proper relationship with a proposed wall or partition between the ceiling and floor of a building.

Other objects of the invention will be apparent by reference to the following description and the accompanying drawings wherein like reference characters designate corresponding parts, and wherein:

Referring tothe drawings by reference characters, and particularly to Figs. 1 through 5,\I0 indicates the iioor and II indicates the ceiling. A pair of blocks or plates I2 are shown mounted against the ceiling II. shown positioned against the face of a door frame I5 each stud being aligned withthe outer edge of each jamb of the door-frame. Two pair of supporting clamps I6 and Il are illustrated attached to the studs I4 and clamping the door frame I5. The clamps I1 are shown supporting the end of the studs I4, while the clamps IB are shown mounted on the top lintel portion of the door frame I5 clamped'about the studs I4. Clamps I6 are used to grip the studs I4 in a tight Yrelationship and have adjusting members permitting anoperator to induce a compressive force between the plates I2 and the. lintel of the door frame l5, while the clamps I1 are used to keep the studs I4 in alignment with the jambs of the door frame when the compressive force isinduced in the studs I4 to position the door frame I5. A better understanding of the clamps laand I1 may be had by referring to Figs. 4 and 5. Fig. 4 illustrates the clamp I6 with a stud I4 shown in dotted lines. The clampv I6 is comprised of two parallel sides I8 and I9 and the: end piece '20. "A ninety degree angle piece 2I, having twosides 22 and 23, is amxed by welding or otherwisevto the side I8 of the vclampI on its outer surface and is provided with apertures 24 and 25. A pair of rectangular shaped apertures 26 and 21 are provided through the walls I8 and I9 as well as thev side 22 of the angle 2|. Their size approximately matches a rectangular cut masons nail 'when fully inserted in saidv slots. The sides I8 and I9 are further provided with a plurality 'of parallel pairs of slots 30, 3| and 32 so formed that a bolt 33 maybe moved the full length'of any pair of slots 3B, 3I or 32. The slots are all formed with a slight angular formation inclined ydownwardly toward the web so that the bolt 33, `when moved from the upper portion of any pair of slots to the lower portion, will move in a path to reduce the area betweenV the wall 20 and the shank of the bolt 33. Thefpair of slots 30, 3I and 32 are spaced in such a relationship that a 2 x l stud Amay be positioned between the wall 2D and the bolt 33 when in the slots 32, or-a 2 xv 3 stud may be similarly positioned when the bolt 33 isin the slots 3|, or a 2 x 2 stud may be similarly positioned when the bolt 33 is in the slots 30.

A pair lof studs I4 are4 aperture 24 or 25, according to the alignment..

oi.' the clamp I6 with the lintel of the frame I5 so that the head of the bolt 35 restsyonthe.- top,

edge of the frame, as illustrated in Fig. v.3. By

adjusting the bolt 35 a sufficient degree of compression may be placed througnthefstuds; Ikon; t. the lintel of the door frame I to retain the... frame in a set relationship. However, referring*- to Fig. 5 it is necessary to position the clamp I1, whieh-fisfcomprisedf of =al illeshapedrmember, that ts the two inch side ofaether vtliezi2x2g`2x3l orf2x4., and; may vbenailedf to tlfielvendV o'fi the ..stud..
